Hi,
  In my experiments I am reading the response size with Content-length field as below: ( Traffic
server-7.0.0)

case TS_EVENT_HTTP_READ_RESPONSE_HDR:
          {
            if (TS_SUCCESS == TSHttpTxnServerRespGet(txn, &hdr_bufp, &hdr_loc)) {
                TSMLoc loc = TSMimeHdrFieldFind(hdr_bufp, hdr_loc, "Content-Length", -1);
                sd.status_code = TSHttpHdrStatusGet(hdr_bufp, hdr_loc);
                if (TS_NULL_MLOC != loc) {
                    sd.c_len = TSMimeHdrFieldValueUintGet(hdr_bufp, hdr_loc, loc, 0 );
                   TSDebug("balancer", " [%" PRIu64 "] %d %d",  smid, sd.status_code, sd.c_len);
                  }
               TSHandleMLocRelease(hdr_bufp, hdr_loc, loc);
          }

          }
And in Transaction close event:

  case TS_EVENT_HTTP_TXN_CLOSE:
              {
                                        resp_size = TSHttpTxnServerRespBodyBytesGet(txt);
                TSDebug("balancer", "[%" PRIu64 "]Server response size %d", smid, resp_size);
               }

The output from Traffic server:

[Jul 15 10:15:44.450] Server {0x7f7b7309b700} DIAG: (balancer)  [176] 200 334496
[Jul 15 10:15:44.455] Server {0x7f7b7309b700} DIAG: (balancer) [176]Server response size 334496

I am using load balancer plugin for my experiments.

Thanks

hi all,
I want to get the total http response size (i.e. size of headers + body). For this i tried
using below two api's :
TSHttpTxnServerRespBodyBytesGet(txnp)     //always returns 0
TSHttpTxnServerRespHdrBytesGet(txnp)       //seems to work fine

Are there any known issues in using the first api ? Is there any alternate way to get the
total size (headers + body) ?
thanks,
gaurav
